Abstract

Human body contains around 1013 number of cells. All nucleated cells of the human body contain DNA and hence any biological material left in the crime scene can be collected and used as a biological evidence for DNA typing analysis. However, the samples should be collected properly to avoid contamination or degradation. With the advent of PCR technology, a trace amount of biological evidence present in a crime scene can also be useful due to the amplification process and reaching the detection limit of the instruments. In this regard, touch DNA technology is also in practice currently for small amount of DNA present in the samples.
